I'm not sure why this is surprising. In the US we try to maintain inflation at a target rate of 2%. For commodities where the costs aren't able to keep pace with inflation you'd either expect prices to double every 35 years or for the product to be half-ish the size (assuming labor costs scale by size). It's a 99 cent candy bar so... I think inflation rate and costs of lots of things due to oil has jumped so much in the last few years that both the costs have gotten mouth watering and sizes have gotten noticeably smaller. But I prefer either of those to leveraging even more low cost filler, which I assume is the other option. I honestly think in the US portion sizes tend to be larger than I need here so I'd honestly prefer if they lowered prices and dropped sizes to something reasonable.
